Tuna is a good source of many healthful nutrients, especially selenium, potassium, Vitamin D, Vitamin A, Vitamin B12, and omega-3 fats (the good kind of fat). For essential B12, a serving size of 100 grams of tuna fish provides 2.2 micrograms.
If you need easy-to-peel eggs and you have fresh eggs, you might want to try steaming the eggs for 15 minutes. Pour an inch of water into a pot and insert a steamer basket.Bring to a boil. Place the eggs in the steamer basket, cover and steam for 15 minutes (more or less, check!).
When you boil an egg, a physical change occurs that causes it to harden. The time it takes to hard boil an egg depends on the size of the egg. Give the egg time to reach room temperature, about 12 to 15 minutes. Place the eggs in a pan of water and give the water time to boil. It should take eight to 10 minutes for the water to begin to boil, less time if you cover the pan with a lid. You can also add salt to the water to encourage the water to boil faster.
